Verification Measurements
(Continuous Sweeps)
These measurements are performed in each wavelength range in
continuous sweep mode, and require 5 consecutive scans at each speed
under test. The current list of sweep speeds to be tested is:
5 nm/s, 20 nm/s, 40 nm/s, 80 nm/s.
The corresponding averaging times of the power-meters should be set to
the maximum values compatible with the required sweep speed and
wavelength step,
that is: 100
µs, 100 µs, 25 µs, 25 µs respectively.
For each sweep speed and each repetition the detailed operations are:
15 Set the TLS and PWM to the power settings specified at step 6;
16 Set the power-meter wavelength to 1500 nm
(hp816x_set_LambdaScan_wavelength);
17 Enable the selection of all sweep speeds
(hp816x_enableHighSweepSpeed);
18 Select the current sweep speed;
(hp816x_setSweepSpeed);
